CHICAGO (CBS) -- A mother was under arrest and undergoing a mental evaluation Thursday night, after her 7-month-old baby was found with a serious head injury.
Earlier in the day, police found two older children alone in the same Pullman neighborhood apartment where the baby was later found.
As CBS 2's Charlie De Mar reported, the 7-month-old was found unresponsive with blunt force trauma to the head and was in critical condition at the University of Chicago's Comer Children's Hospital Thursday night.
At 1 p.m., Chicago Police were called to an apartment building on the 900 block of East 104th Street. Two children – a 5-year-old boy and a 7-year-old girl – were found wandering around the building.
Police couldn't find their 7-month-old sister or their mother. The older children were taken to Roseland Community Hospital for evaluation.
"I see the lady in the street yelling for help, screaming," said Lashaun Foster.
Lashaun Foster lives in the building and recorded cellphone video of the disturbance outside her window.
"I don't know if she's in her right state of mind, but I feel bad for that lady," Foster said.
Police and the Illinois Department of Children and Family Services returned to the building at 6:30 p.m. for a wellbeing check. That was when they found the mother and the critically injured 7-month-old inside.
Foster said the mother was screaming and not making sense. De Mar asked Foster what the woman was saying.
"She want to die, kill her; she had COVID; 'Get back! Get back! She don't know you!' She said the police was against her," Foster said.
The mother was taken into custody and also taken to St. Bernard Hospital for a mental evaluation.
